Abstract

Bei einer zugfesten Rohrverbindung (1), mit einem ersten Rohr (2), das ein Spitzende aufweist, welches sich in ein Muffenende eines zweiten Rohres (3) erstreckt, wobei das zweite Rohr (3) eine umlaufende Wulst (4) aufweist, und mit einem Haltering (6), welcher die Wulst (4) des zweiten Rohres (3) in der Art übergreift, dass der Haltering (6) in axialer Richtung an dem zweiten Rohr (3) gegen abziehende Kräfte formschlüssig gesichert ist, und wobei der Haltering (6) einen Krallenabschnitt (7) aufweist, welcher sich bis über das erste Rohr (2) erstreckt, und wobei in dem Krallenabschnitt (7) wenigstens eine in die Oberfläche des ersten Rohrs (2) eindringende Haltekralle (8) in der Art angeordnet ist, dass das erste Rohr (2) gegen abziehende Kräfte formschlüssig gesichert ist, schlägt die Erfindung vor, dass der Haltering (6) aus wenigstens zwei Teilringen (15) gebildet ist, die sich jeweils über einen Teilumfang des Halterings (6) erstrecken, wobei zwei benachbarte Teilringe (15) durch Spannmittel (16) miteinander verbunden sind.In a pipe connection (1) with high tensile strength, with a first pipe (2) which has a spigot end which extends into a socket end of a second pipe (3), the second pipe (3) having a peripheral bead (4), and with a retaining ring (6) which engages over the bead (4) of the second tube (3) in such a way that the retaining ring (6) is positively secured against pulling forces in the axial direction on the second tube (3), and wherein the Retaining ring (6) has a claw section (7) which extends beyond the first tube (2), and wherein in the claw section (7) there is at least one retaining claw (8) penetrating the surface of the first tube (2) of the type is arranged such that the first pipe (2) is positively secured against pulling forces, the invention proposes that the retaining ring (6) be formed from at least two partial rings (15), each of which extends over a partial circumference of the retaining ring (6). , wherein two adjacent partial rings (15) are connected to one another by clamping means (16).
